.sp
An environment is a way to map an organization\(aqs real\-life workflow to what can be configured and managed when using Chef server\&. Every organization begins with a single environment called the \fB_default\fP environment, which cannot be modified (or deleted). Additional environments can be created to reflect each organization\(aqs patterns and workflow. For example, creating \fBproduction\fP, \fBstaging\fP, \fBtesting\fP, and \fBdevelopment\fP environments. Generally, an environment is also associated with one (or more) cookbook versions.
.sp
The \fBknife environment\fP subcommand is used to manage environments within a single organization on the Chef server\&.
